I realise that but I have to run this via codesign cli. If I change that setting in Xcode, are you saying that codesign cli will recognise it? This binary isn't even vaguely an Xcode project but could still be codesigned before OSX 12. There are many such projects that distribute OSX binaries which were not made in Xcode but which have to be signed for recent OSX. This works perfectly fine but can't be done since OSX12 it seems ...
